Upgraded to FreeBSD-10/gcc48. One project puts a dozen object files in a
static lib via ar, but now that takes a long time, and it's not CPU.
“time ar -v -c -u -q ...” : 362.62 real 0.11 user 0.82 sys.
“time ar -v -c -r -u -s ...”: 407.94 real 0.13 user 0.80 sys
iostat's numbers don't look to impressive to me, but my ISP says they're
normal. 'dd' writes to the disk plenty fast. I moved off the RAID-1 but
it made no difference. I have 64G swap and it doesn't get touched.
Truss shows it reading the input files and writing the output, but write
times are all over the place. truss -D ...
0.000031869 write(3,...,10240) = 10240 (0x2800)
0.083054581 write(3,...,10240) = 10240 (0x2800)
0.000029723 write(3,...,10240) = 10240 (0x2800)
0.841429575 write(3,...,10240) = 10240 (0x2800) <-- seems pretty slow!
0.000015954 write(3,...,10240) = 10240 (0x2800)
0.000022723 write(3,...,10240) = 10240 (0x2800)
Truss shows 800 write's that take over 0.7 sec, similar to the above.
Where's my problem? What to try next? Is it even the disk?
Thanks in Advance,
-Jim
